As much as Chinstrap Ninjas love prospects coming out of nowhere and career years, baseball is a predictable animal.

There are many, many certainties in baseball and fantasy baseball, chief among them: Victor Martinez will get hurt, Chone Figgins will steal a base (or 20) and Erik Bedard will be rehabbing somewhere.

Let’s discuss more on the obvious and, of course, not-so-obvious from around fantasy baseball Sunday:

Jair Jurrjens – Likely to return Wednesday, dumping Kris Medlen or Kenshin Kawakami to the bullpen. Kawakami has been bad this season — he snapped a personal 11-game losing streak on Sunday. Medlen is 5-1 with a 3.15 ERA and 54 Ks to 13 walks. Simple math.

Victor Martinez – Fractured the top of his left thumb Sunday. He’ll be reevaluated today but a trip to the disabled list doesn’t seem likely at this point.

Jhoulys Chacin – Struck out a career-high 12 batters, unfortunately he also allowed five runs, two earned, and eight baserunners in six innings. The Rockies have lost five of his last seven starts and seven of his last nine, which is why he may be the odd man out when Jorge de la Rosa returns from the DL.

Tyler Colvin – Needs a full-time job. Colvin went 3-for-5 with four RBI, two runs and hit his 10th homer on Sunday. The left-handed hitting Colvin hits both righties (.290) and lefties (.314). He’ll be an OF2 in 2011.

Erik Bedard — Threw a bullpen session and will pitch in a rehab start at AAA Tacoma on Thursday. Unless you get points for time missed due to injury, a ninja should not consider any news on Bedard relevant to their fantasy team.

Pablo Sandoval — Hitting .238 with three homers in his last 47 games, according to a report on KFFL.com. We called him a bust in the preseason, but even we didn’t expect this. He’s a considerable — and considerably risky — buy-low candidate at this point. If you have the roster flexibility to let him sit on your bench while he figures things out, make a play. He could pay serious dividends in the second half.

Jenrry Mejia — Saw about 30 headlines talking about Mejia this morning: He left a AA start with a shoulder injury. … The Mets won’t trade him without a “negotiating window,” when they’ll see if they can sign him to a longer deal … Whatever. Mejia is a top prospect in the Mets system. He was rumored to be closer of the future earlier this season, but has started 42 of his 49 minor league games — including every one since 2008. He wasn’t super effective in AA last season or the majors this season and has never pitched in AAA. He is no Stephen Strasburg, but because he plays for a New York team, he gets SS publicity.

Chone Figgins — Stole his 20th base on Sunday, giving him 300 for his career. Figgins is hitting only .232 with 37 runs. I would never draft Figgins. Ever. But I’d think about buying low. He should be hitting at least40-50 points higher and should score 50 runs in the second half. Oh, and elite base thievery at fair market value.

Mike Gonzalez — Orioles closer was pretty disasterful — two runs on two hits — in his rehab stint for class A Aberdeen. It’ll take a while for that strained left throwing shoulder to be right.

Will Venable — Hit his eighth homer on Sunday. He now has four homers and is 8-for-24 (.333) with six runs, 12 RBI and two stolen bases in his last seven games. Because of his average he’s not a long term option, but he’s a viable waiver add while he’s hitting.

Rickie Weeks – What was said about Venable, except with these statistics: 9-for-18, six runs, six RBI, two homers in his last five games.

Clay Buchholz — Has a minor lower hamstring tear. He won’t need the DL and will be rested leading up to his July 6 start. “Tear” sounds a little risky to me. If he makes that July 6 start, you should rest him, too.

Brett Gardner – Will have X-rays on his bruised right forearm today. Initial stories said it was a bruise and nothing else. Monitor this developing situation. Chad Huffman and Colin Curtis stand to reap immediate benefits if the injury turns serious.

B.J. Upton – Caught lallygagging on a fly ball that turned into a triple and got into an altercation with teammate Evan Longoria. Upton has really be slumping at the bat of late, so you might not have him in your lineup anyway, but a suspension may be on the way.
